Assume that box B starts from rest at a distance r = 0.5m from pin A. At time t = 0, the arm is at an angle of 0= 0°, and then starts moving at a constant angular acceleration of = 2 . Note that the motion occurs in the vertical plane and that the coefficient of static friction between the box and arm is l = 0.5. Calculate and plot the angle at which the box begins to slip. You must show all diagrams such as the Free Body Diagram/s and Kinetic Diagram/s. Hint: You might want to start with the kinematics and express 0 and as a function of time. Solving the equations of motion might require you to solve a nonlinear equation (in time) which you can try do by plotting the resulting equation as a function of time and finding at what time the function becomes zero.
